Brushless Maxx hesitates

[steve050773]

Serum - I'll take some detailed pics tonight. The receiver (and the receiver pack or ubec) is at the opposite end of the truck from the controller, near the rear shock tower. The controller is at the front. Both are mounted using velcro to try and isolate them from the aluminum chassis. I have removed (and have always had it removed) the black bec jumper on the underside of the controller (near the programming jumper).

I have not tried re-programming but I should be able to try that tonight as well.

So is there no way to test the quality of a solder join as nl12 suggests?
